printf and scanf funtions are pre defined in c and the functions or statements that are predefined are embedded in some header files.printf and scanf are embedded in stdio.h header file.Header file is nothing but a library where the code of predefined statements or function's codes are stored.So when we write printf/scanf stdio.h header file automatically run the code of printf/scanf.Main function receives the value written by printf and scanf.
